As far as I'm concerned, I find the following network architecture to be pretty good/common practice:
  • 1 public IP per physical site (more if you want backup lines)
  • VPN between all the physical sites (to interconnect offices)
  • 1 internal network per "service" (development, testing, benching, ...)

This architecture is easy to maintain and understand. The hardest part here is to figure out the mask for each internal network.

For electrical/cooling system, I must say I'm no expert. All I know is that our server room has its own electrical circuit that's independent within the building, and we have 3 air conditionners in the room to keep it at around 20°C.

For OS deployment, well, it depends on the purpose of the machine. We actually install the OS by hand every time, be it a windows computer, centos server, or esxi, or whatever we need.
For most linux server, we then use a configuration management system to "bootstrap" the machine and give it a purpose.

Regarding storage, you don't have much more choice than buying some here and there, or rely on an outsite service that will handle that for you.
I personally (like, at home) use 3 backup methods:

For my desktop, everything is both on my acutal drive, on a second harddrive INSIDE the computer, and on a usb drive sitting on my desk. It means that if my house burns, I'll loose my data...
The problem is that for the amount of data I have, online backup solution are too expensive... My plan was to buy cheap boxes to get running in house of people I know, or build a "circle of trust" with people online to backup my things in multiple places.
I'm still "working" on that part...

For servers, I use tarsnap to backup my server's configuration and data. The service is pretty cheap, and I trust the guy.
My main server (the one with the most diskspace) fetches data via rsync from its peers over a VPN to a local folder, then weekly send the data to tarsnap server.
I then get a report of the uploaded data in my mail, as a reminder that my backup is working.

That's all folks!
